Connecting to Power
CAUTION
The wiring from the power source to the amplifier must run through an inline fuse or circuit breaker (not
included) as close to the power source as possible. You must connect the positive wire to the fuse or circuit
breaker. Connecting the amplifier to power without an inline fuse or circuit breaker may result in a fire if there is
a short in the cable.
If the amplifier is powered by a battery, you should connect it through a fuse or circuit breaker rated for 15 A.
If the amplifier is powered by a source other than a battery, use a breaker or fuse rated no higher than the max
current of the power source.
NOTICE
You should make all wiring connections using solder and heat shrink tubing or another type of secure
waterproof connector.
You should use 16 AWG (1.31 mm
2
) copper-coated aluminum wire (not included) to extend the power and
ground wires for most installations. For long power-cable runs, you should consider using larger-diameter
(smaller gauge number) wire to minimize power loss. If you are using pure copper wire instead of copper-
coated aluminum, you can use a smaller-diameter (larger gauge number) wire because of the increased
material conductivity.
You must connect the REMOTE ON wire from the amplifier wiring harness to either the AMPLIFIER ON wire
from the connected stereo or to a constant 12 or 24 Vdc power source using a switch. Connecting to the
AMPLIFIER ON wire is recommended to avoid a popping sound when the stereo turns on or off.
NOTE: The stereo and the amplifier must both connect to a common ground or the REMOTE ON signal will not
turn on the amplifier with the stereo. If the amplifier is connected to a 24 Vdc source and the stereo is
connected to a 12 Vdc source, make sure that they connect to a common ground for proper operation.
1 Route the red POWER wire
to a circuit breaker or fuse rated for 15 A , and route the black GROUND
wire
to the battery.
2 If necessary, route a wire between the circuit breaker and the battery .
3 If necessary, route the wiring-harness plug to the amplifier.
Do not connect the wiring harness to the amplifier until after all of the bare wire connections have been
made.
4 Connect the black wire to the negative (-) battery terminal.
5 Connect the red power wire to the fuse or circuit breaker, and connect the fuse or circuit breaker to the
positive (+) battery terminal if necessary.
6 Connect the wiring harness plug to the amplifier.
